SEPARABLE FRAME FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 607,325, dated July 12, 1898. i nmion fil d August 19, 1897. SerialN'o. 648,824.. (No model.)

T0 at whom it may concern:

Be it known that I, BURRF. BARNES, acitizen of the United States, residing at Circleville, in the county of Pickaway and State of Ohio, have invented certain new and useful Improvements in Separable Frames for Bicycles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in bicycles, and especially to a separable frame for the safetybicycle, thereby rendering it possible to reduce the space required for packing the frame when it is desired to transport the Wheel.

More particularly the invention resides in the construction of the frame which is capable of being spliced, and the parts of the tubing securely held together by a suitable looking key or lug engaging in a slot in a collarheld over the meeting ends of the tubing of the frame.

To these ends and to such others as the invention may pertain the same consists, fur: ther, in the novel construction, combination, and adaptation of the parts, as will be hereinafter more fully described and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which- Figure 1 is a side elevation of a frame of a bicycle constructed in accordance with my invention. Fig. 2 is an enlarged detail View of the lower jointed tubing. Fig. 3 is an enlarged detail view of the coupling on the upper or horizontal tubing.

Reference now being had to the details of the drawings by letter, A designates one section of the horizontal tubing of the frame, and B the second section, and a is a union or coupling-collar. The meeting ends of the said sections A and B are provided with integral lugs C C, over which the collar a is slid, the lugs bein g guided in the slot b,which is deflected at a right angle at its inner end and has its walls slightly inwardly tapered or wedgeshaped. This angled 'portion of the slot is provided to receive the lugs after the collar has been pushed over the meeting ends of the said tubes and a part revolution imparted to the collar, the'lugs being forced in the angled end of the slot and securely held in place.

The lower portion of the frame leading to the head of the frame is madeup oftwo pieces of tubing D and E, each end of which pieces is recessed away a suitable distance from their ends, forming the fiat contacting surfaces '1 ands, with the flat end of the tube E designed to rest against the shouldered portion of the tubing D. Located within the tubing E is a pin on, over which the notched end of the filling g in tube D is designed to engage, as shown in Fig. 2 of the drawings. Secured to the flattened surface of the tubing, on diametrically opposite sides thereof, is a pin it, which is designed to be seated in a notch t'in the tube D when the tubes are held interlocked and in a horizontalrelation.

In order to hold the tubes A and B together more securely and make the connection more rigid, it is my purpose to insert a fillingfin the tubes, one end being securely fastened to the tube B, while the other end will be free to pass Within the bore of the tube A, as illustrated in the drawings.

Having thus described my invention, what I claim to be new, and desire to secure by Let ters Patent, is y 1. In a separable frame for a bicycle, the tubes D and E, a filling in one tube havinga notch near its free end, a pin mounted in the end of the other tube on which said notched end is designed to engage, combined with the horizontal tube-sections and means for h0ld=- ing same together, substantially as shown and described.

2. In a separable frame for a bicycle, the combination with the hollow tubes D and E, the fillin gin tube D and provided with a notch 72, the pin m mounted in the tube E, and designed to be engaged by the said notched por tion in tube D, the pin h and recess 71 to re- In testimony whereof I aflix my signature ceive the same, of the tubes A and B, the 1111- in presence of two Witnesses. ingfin tube B, lugs C on diametrically oppo- BURR F BARNES site edges of the ends of the said tubes A and 5 B, and the slotted collar (4 adapted to fit over \Vitnesses:
